coMrUtriNe-Macninn Application filed. April 20, 1816. :Serial No. 92,522..

To all whom t may comen/t:

Be it known that I, lnonon R. Woon, of the city of Montreal, Province of Quebec, lominion of Canada, have invented certain new and useful Improvements in Comput ing-Machines, of which the following is a fall, clear, and exact description of the saine.

My invention has for its object to provide a comparatively simple and easily operated machine by Which` the sum of a known quantity and a. given value per unit of the quantity may be computed and recorded; and to alford means of this nature applicable to a merchandise scale .whereby a ticket or hill may he issued to the purchaser :if each specifically weighed quantity, WhichA will give irrefutable information of the Weight of the merchandise purchased, the rate per unit of quantity and the total price thereof. Y

To this end the imfention may be said, broadly, to consist of a movable 'unitary indicating computing ineinher havingr a. divided and subdivided surface containing in its` divisions and subdivisions respectively senarated devices qnantity and fractions of units of quantity the value of which are computable, and units of value and fractions of units of value predetermined to have' a range sufficient to cover the scope of the quantity indications. Dispo-sed in fixed position relatively to this member are printingr mechanisms, and intermediate mechanisms adapted to effect operative connections therebetween and the quantity andvalue indicatii'ig devices; controllingand lockingr mechanisms automati* cally enacting. With the lirinting mechanismsl to present the results of the computations; and manually operated means .for operating theinterrnediate mechanisms.

More specifically stated, ii'hen applied to a computing scale, the movable indicating cy inputingj` member is in the form of the Well known balanced cylinder rotated hy the platforin of the scale to automatically' anse one of a circumferential series of circumferentlally spaced lines in its perimeter and parallel to its axis and arranged in certain predetermined angular positions on the per inieter and in certain relation with depressed positions or" the plattorni, to assume a position 1n guxtaposition with a graduate Vvscale ofrates or prices carried by the frame or borings, the sockets representingy the units of' of the machine in lined position relatively to the cylinder. Accordi' Vny invention the .surface of the cylinef l t cept for a series of circus' axially spaced distinct and l tu l .ings o group being of' diiierent depths while the groups are circumferentially arranged and cach depth has a certain specific. 'valueas 'to quantity or price; and certain portions el' the perimeter of 'the cylinder represent the ordinal zero. A series of rockers corresponding in number to the groups of sockets or borings of each series are in operative relation with certain pins in a series and are arranged in parallelism with 'the axis fof the cylinder. Y These rockers f :onstitutc an operative intermediary between a manually operated device and the pins, whereby 'the pins are inserted into the sockets or borings or caused to bear upon the perimeter of the cylinder between the sockets, and conse quently thereby adapting Jrhe sockets or hor ings to control the printing mechanism. A carrier for the pins immovable radially relatively to the nidi-:ating metalic" and movable parallel to thc surface or pc thereof, enables the operator to shirt the pins to registering,r position with any par ticular series of price sockets or liorings. 85.

These distinct and separate sockets or non l ings which `with isolated adjacent portions ot the perinwtcr oi' the movable nieinher forming 'the groups of value or weight indi 'atingl device and the pins and sockets, or their' equivalents, and the s parately carried controlling and printing; mechanisms, are the spirit and essence ol' my invention.

For full comprehensiiin, however, of .my invention, reference must be ha'dtothe accompanying drawings forming a part of this specification inl which similar reference characters indicate the saine parts, and wherein: .Y

'41s f t r machine Why The pl operated art, with means connecting the 4sanne to t e print Wheel operating mechl il anism to operate them successively. There are also ribbonV feeding and reversing mechanism, and aper feeding and cutting mechanism w ich .may be of a form found in cash registers at present onv themarket and other similar machines having paper:- strip printing, feeding and cutting mechanisms, and as these form no part of my invention they are indicated lfor illustrative purposes only.

An. operating lever is fulc'rumed on a shaft 51 carried in the frame of the machine, and has a tail l52 pivoted to a tail 53 of'a second lever 54 ulcrumed upon the shaft 55 and ivotally connected to the lower end ofV a yo "e connected at itsl upper end to the cross bar 6l to which are pivotally connected the lower ends of ten independent and distinct pull bars 62, 63, 64, 65, 66, 67, 68, 69, an 71 operating the various rockers and ins of the machine. These mechanisms are :divided into three sets, one set for the pins -.l8,`19 and 20 and the other two sets for other pins to be presently described.

AReferring first to the pins 18, 19 and 20 andthe rockers 35, 36 and 37, it should be understood that the mechanisms controlled by these pins and operated by the lever 50 are thel same in all" respects and only one need he described therefor. Taking pull bar 69 and rocker 37 as an example. T bar is operatively connected at its upper eno to the rocker and controlling and locking mechanism for the print Wheels and approximately midway of itsv length to the print Wheel operating mechanism. Means operatively connecting the bar to the rocker consists of u link 7 5 piv'otcd as at 76 a short distance in- Wardly from the pivot shaft 38 of the rocker and at its -lovveruend to a pivoted pin 77 slidably engaging a slot 78 in the upper end of the bar. This pin 77 also has pivotally connected thereto the tail 79 of a lever 8O nlcruzned on the .shaft 8i mounted in the frame of the machine. This tail is operatively connected to the pull bar 69 by a 'helical spring 500. In order to obtain the proper working of my machine, the distance between the points and 76 inust be equal to that between points 77 and Sl and the length of the side arms of rocker 37 and automatically follow the lever as it is raised and to be depressed as the lever returns to its normal position. This limiting pin engages a spiral lock having a pinion. 110 secured rigidly thereto, the member thus formed being rotatively mounted on a shaft 112 carried by the frame of the machine. The edge of the lock is divided into tenths represented by uniformlyangularly spaced teeth e6, 97, 98, 99, 10o, ici, 102, 103, 104 and respectively, each tooth corresponding with one of the figures on the print Wheel consequently when the pin is raisedto an extent permitting rotation of the lock 95 two teeth the print wheel .is then also :tree to rotate until the ligure 2 cornes opposite the printing point. i

A sector rack 600 pivoted to the frame of the machine interineshes with the inion and is operatively connecte to pull-bar 69 by a lever consisting of two parts, and 116, hinged 'together as at 117 with its hinge pin serving as a fulcrum for the lever, such hinge pin being supported in the frame and extending through the other corresponding mechanisms. These hinge lever parts are connected yieldingly together by a helical spring 120 secured at its opposite end to lingers 121 and 122 on' the respective lever parts the tension of the spring being suflicient when the pull-bar 69 is pulled to raise part 115 until it is stopped by the engagement of the pin 90 with the spiral lock 95. With this arrangement different degrees of movement of the lever parts is accommodated the pivoted ends oir' the two parts being out away to allow further movement of the part 116 if necessary after the part 115 has been stopped. rThe connection between the lever part 116 and the pull rod-,is a pin 125 Working' in a slot 126 which has for its purpose to delay the operation oit' this hinge lever until after the lever 8O has completed its movement. This detail description covers the inechanism for controlling and locking' the print Wheel ol this particular rocker but does not operate it, The operation of this print Wheel is effected by a pinion i3() corresponding to the pinion 11() and rigidly connected to the print wheel 131, the periphery oi" the Alatter being divided into tenths represented by printing type indicating respectively l, 2, 3, el, 5, 6, 7, 8, 9, O, and this print wheel and its-pinion beingrotatively mounted in the portion of the machine frame in position to have the sector rack 60() intermesh therewith thereby securing the operation of this type `vheel in unison and under the control of th,- controlling' and locking means.

y. In connection with this print Wheel is a 'ies printing mechanism to operate immediately' after the print wheel has been adjusted and set. This printinfr mechanism consists of a hammer 150 carried by the end of a' lever ou the siieii 152 gjefereiiiy sub- 'aiiy iii iiie seme 'vertieiii piene es 'the i? tiie lever ii being ioi'n'liiily n yie'ii'ii` eoii'zwt with e sito@ 'iby e, i eoii'eeezefi :it one emi io 'the lever mid et iii-s opposie end to the 'frame of the 'Qhie ievei Tous zi (iowim'aifiiiy eX- g with a. lateral Engel? :m51 .inizi/imei is yieic'iingly heici iG. eiioemeni', i' etraroi-iie spying 'M0 ooiiiieeeci et its s #io pins M1.. 142. on the here" mei' und. level. espee-ively.

Eri-ch rack 225 is connccted to one of the pull-bars 62, G3, 64 and @5 hy a lever consisting of two parts corresponding with parte and 116. Y

The print wheels just described are operated in exactly the same manner as the r'int wheel 4131, the arrangement of parts eingthe same. 4

The case of this machine', in order to accommodate the mechanism of the scale, has edrnm 250 containing the cylinder, andfupwardly und laterally extending boxl1ke structure, 251, in addition to the usuel standard, 252, and hase, 253, the drinn having o single glazed aperture, 254, through which the operation ol' the strip 190 bearing the hgnres representing in pounds and ounces the weight of the merchandise may be seen resting upon the platform. n The compute.v4 tions are printed upon n strip olf' paper 30() which extends between the' hammer of the printing mechanism and the inking ribbon 301.

-ous print Wheels to bring the The paper feeding end cutting nieclmnism and theI inkingmechanism are) not illustrated 1n detail as they do not form part of l Operation. l

I Will now describe the operation ot n. computing platform scale with my invention applied thereto.

The merchandise 'being sold is thrown on the platform, the depression of which rotetes the cylinder 'in the usuel wey :1nd brings the figures indicating the weight ot the merchandise in juxtaposition with the apertnre 254, the entire mechanism of the scale secnring'this result beingdn coinnion use and forming no part of this invention.

.imultaneonsly with the positioning and set ing of the cylinder, the proper line ota sockets is placed in the verticalplnne of thenxis of the cylinder, these sockets heing or" depths calculated to govern the extent to vwhich the pins 30, 31 and 32 may be inserted into the sockets. The carriage is then shifted until the pins register with the rate et which the merchandise is sold. This Will also place the pins V177, 178 l.ind 179 in coincidence with sockets in the ro 'kers 180, 181, and 182 which first action will be the depression oi ell the rockers to the extent permitted by the 'pins and consequently the adjustment of the vsriroper type into nlineinent. ...The continuer? of this lever causes the hammer to be yibrnted and the total weight ot the'inerchnnilise, the

rete at which it is sold and the total price to be printed on a. slip.

This slip ot paper is usually carried in a ribbon of paper wound on drums or spools and the t pe is inked by the inking ribbon suitably ed and reversed and the printed slip' cut ofi', by cutting mechanism, all of which are in cominon use in' Scales, cash registers and other machines for simile r puroses.
